But what type or make of fan will be the best , ie give you the coolest temps with the least amount of noise for the job ?

Bond is right the sp-120's are great at lower voltage and have great SP which yields good temps. Like he said though at full speed they can be rather loud. I really don't see to much difference between 2 sp-120's and 2 Helix pwms on my h220. About 1-3c difference, the helix's at the stock rpms vs the stock sp-120 rpms IMO seem to be less loud. Again he is also right about not really needing P/P because the most iv seen is about 2-3c difference in my setup. Thats because of the thickness of the h220/h320 rad.. On my h70 before with sp-120's when I put it in p/p it was about 4-6c difference from just one fan. So I think it depends on the radiator size. Bond is a smart dude, Id listen to him but make sure you lower the rpm's on those bad boys if your a noise freak!

OMG... every which way conceivable, an h320 will absolutely destroy an h110... larger rad, better rad materials, more powerful pump, more fans... just no contest whatsoever. An h220 vs an h110 is at least a somewhat fair fight, but against an h320... fuggetabout it.

Push pull is overrated on thin rads and a must on thick ones !. Look at the tests... It provides maybe 1-2 degree difference. But if you insist on going push pull make sure you get the same fans all around.

fixed it for you

I do have a pair of nf-12 and while they work good they do produce noise while attached to radiators, especially above 800 or 900 rpm. I would say they are not the best option in terms of performance (thermal x noise) and cost out there. I would rather go with gentle typhoons ap-15 and drop speed to 1000-1200 rpm. You will get much better cooling with less noise and less cost too. In fact that was the route I took it for my two 240 mm rads.
